Man not guilty of Perth 'DJ Suave' murder

A man who fatally stabbed a 41-year-old Perth DJ after they argued over a lost envelope containing cocaine has been acquitted of both murder and the lesser charge of manslaughter, having claimed he acted in self-defence.

Jaime Rodolfo Fernandez, an event organiser known as "DJ Suave", was found under a running shower in his Tuart Hill apartment in July 2016, four days after he was stabbed to death.

Defence lawyer Jeremy Scudds told a Supreme Court of WA jury earlier this month Fernandez was a drug dealer and a fight broke out between him and Victor Amaya, 28, when his client went to the unit to deliver event tickets in envelopes.

Mr Scudds said Fernandez became angry because Amaya had lost one of the envelopes, not realising it contained cocaine.

"He got drawn into an unfamiliar world that he'd never experienced and an incident arose," instructing lawyer Sutherlan Scudds told AAP after his client walked free on Tuesday.

He said the case was a tragedy with no winners.

"We just ask that he be able to get on with his life," the lawyer said.

Fernandez was at the centre of an Australian legal precedent in 2012 when he was found in the Federal Magistrates Court to have infringed the rights of rap artist Pitbull to integrity of authorship by streaming a distorted version of one of his songs on a website.
